Why Choose This Product?

• Organizations choose the HPE 834976-B22 when building or expanding InfiniBand-based HPC and AI fabrics that demand deterministic performance and minimal latency. Its 36-port 100Gb EDR architecture, Switch-IB 2 ASIC, and SHARP acceleration distinguish it from earlier-generation InfiniBand switches by improving application scalability and distributed computing efficiency. The switch integrates seamlessly with HPE Apollo servers, compatible Mellanox adapters, and existing InfiniBand environments. Because this model ships without power supplies, it is also an economical option for replacement projects or deployments where compatible redundant PSUs are already available, helping lower procurement costs while preserving long-term infrastructure investments.
